Counter-rotating differential electric motor assembly slip ring assembly

Abstract

A rotational slip ring assembly for an improved counter-rotating (CR) differential electric motor assembly is utilized to power an aircraft vehicle or fan for moving a gas and includes two oppositely rotating propellers that may be mounted to horizontal flight and vertical lift-off aircraft or a fan housing in spaces similar in size to mounting spaces for traditional motors having only one propeller and includes a hollow central shaft and slip ring assembly that is mounted either within, slight above, or total above oppositely rotating components and around the hollow central shaft.

What is claimed is: 
     
         1 . A rotational slip ring assembly for transmitting electricity from a first location to a second location, comprising:
 a. at least one pair of electrically conductive disks with each disk having a central aperture that comprise:
 i. a first disk having an inner aperture edge and an outer perimeter edge and 
 ii. a second disk having an inner aperture edge and an outer perimeter edge; 
   b. a first location electrical connection attached to said first disk's inner aperture edge;   c. a second location electrical connection attached to said second disk's outer perimeter edge; and   d. a spindle housing surrounding said pair of electrically conductive disks, wherein said spindle housing permits said pair of electrically conductive disks to rotate on one another.   
     
     
         2 . A rotational slip ring assembly for transmitting electricity from a first location to a second location, comprising:
 a. a set of paired lubricated sintered disks with each disk having a central aperture that are electrically conductive, wherein each pair comprises:
 i. a first disk having an inner aperture edge and an outer perimeter edge and 
 ii. a second disk having an inner aperture edge and an outer perimeter edge; 
   b. a first location electrical connection attached to said first disk's inner aperture edge;   c. a second location electrical connection attached to said second disk's outer perimeter edge;   d. a spindle housing surrounding said set of paired electrically conductive disks, wherein said spindle housing permits said set of paired electrically conductive disks to rotate on one another;   e. an electrically insulating disk with a central aperture positioned between each pair of said lubricated sintered disks; and   f. compression springs held within said spindle housing that urge said set of paired electrically conductive disks and insulating disks together to maintain electrical contact within each said paired electrically conductive disks during rotation of said set of paired electrically conductive disks.   
     
     
         3 . The rotational slip ring assembly according to  claim 2 , where each said second location electrical connection attached to each said second disk's outer perimeter edge are symmetrically arranged about said set of paired disk's central apertures. 
     
     
         4 . An improved slip ring assembly that includes paired sets of electrically conductive disks with each pair separated by an insulating disk, wherein said improvement comprises:
 a. a set of paired disks with each disk having a central aperture that are electrically conductive, wherein each pair comprises:
 i. a first disk having an inner aperture edge and an outer perimeter edge and 
 ii. a second disk having an inner aperture edge and an outer perimeter edge; 
   b. a first location electrical connection attached to said first disk's inner aperture edge;   c. a second location electrical connection attached to said second disk's outer perimeter edge;   d. a spindle housing surrounding said set of paired electrically conductive disks, wherein said spindle housing permits said set of paired electrically conductive disks to rotate on one another;   e. an electrically insulating disk with a central aperture positioned between each pair of said disks; and   f. compression springs held within said spindle housing that urge said set of paired electrically conductive disks and insulating disks together to maintain electrical contact within each said paired electrically conductive disks during rotation of said set of paired electrically conductive disks.   
     
     
         5 . The improved slip ring assembly according to  claim 4 , wherein said set of paired disks contains at least one lubricated sintered disk. 
     
     
         6 . The improved slip ring assembly according to  claim 4 , wherein said set of paired disks are both lubricated sintered disks.
